## Summary description

This VAREM MB040S2P00000000 replacement membrane is designed for 40-liter hydrophore tanks. It serves as a critical component in water supply systems, maintaining stable pressure and protecting the pump from frequent cycling. Made from high-quality, durable materials, this membrane ensures long-term reliability and efficient operation of your pressure vessel system.

## Long description

The VAREM replacement membrane for 40-liter hydrophore tanks is a high-quality component engineered to maintain consistent pressure within water supply systems. By acting as a flexible barrier between the air and water inside the pressure vessel, this membrane effectively absorbs pressure fluctuations, thereby reducing the frequency of pump starts and extending the overall service life of your pumping equipment.
Advantages
This replacement membrane is constructed from durable synthetic rubber, ensuring excellent elasticity and resistance to wear over extended periods of operation. Its design allows for seamless integration into 40-liter hydrophore tanks, providing a reliable seal that prevents air loss and maintains system efficiency. The material is specifically chosen to withstand a wide range of operating temperatures, making it a versatile solution for various domestic and light industrial water management applications.
Suitable for
Domestic water supply systems
Pressure boosting installations
Protection of centrifugal and submersible pumps
Maintaining stable water pressure in residential plumbing
When it may not be suitable
This membrane is specifically designed for 40-liter tanks and will not function correctly in vessels of different capacities. It is not intended for use with chemical substances, fuels, or aggressive fluids that may degrade the synthetic rubber material.
Key specifications
Volume capacity: 40 liters
Maximum working pressure: 10 Bar
Operating temperature range: 0°C to 99°C
Material: Synthetic rubber
Color: Black
How to use
Installation should be performed by a qualified technician to ensure the system remains airtight and pressure-tight. Before replacing the membrane, ensure the water supply is shut off and the pressure in the tank is completely released. Remove the flange of the hydrophore tank, extract the old membrane, and clean the interior of the vessel to remove any debris. Insert the new membrane, ensuring it is properly seated and aligned with the flange opening. Reattach the flange, tighten the bolts evenly in a cross-pattern to prevent leaks, and slowly repressurize the system while checking for any signs of air or water leakage.
What to consider before purchase
Verify the exact volume of your existing hydrophore tank
Check the compatibility of the flange opening diameter
Ensure the system pressure does not exceed 10 Bar
Confirm the chemical compatibility of the water being pumped
Usage recommendations
Regularly monitor the pre-charge air pressure in your hydrophore tank to ensure the membrane operates within its optimal range and to prevent premature wear.
